Struct TypeVar 

pub struct TypeVar {
    pub id: usize,
    pub name: String,
}

Type variable identifier.

Type variables represent unknown types during type inference. Examples: ’a, ’b, ’t1, ’t2

Fields

id: usize

Unique identifier for this type variable

name: String

Human-readable name (e.g., “a”, “b”, “t1”)

Implementations

impl TypeVar

pub fn new(id: usize, name: impl Into<String>) -> Self

Create a new type variable with the given id and name.

pub fn fresh(id: usize) -> Self

Create a fresh type variable with a generated name.

Trait Implementations

impl Clone for TypeVar

fn clone(&self) -> TypeVar

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TypeVar

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for TypeVar

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for TypeVar

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TypeVar

fn eq(&self, other: &TypeVar) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
